Is it impossible to literally scrape a site online? Like say you wanted to supply forged headers and data to an external website (like github) to login and retrieve information

Without a server of some sort this is impossible right?

I understand embedding is possible but that is a specially formatted template isn't it?

I got my first job three days ago and I feel fucking useless.
There's a bug I can't find that shits up everything I've done and is making me feel worthless.

Is this what working feels like?

>>55496562
i wonder how the staff at that store reacted when they saw the name of the video. i bet they were so excited for it too

>>55496574
are you unit testing? a bug can only be so un-findable if it's in a single function

>>55496574
I work in an office doing office work and it's awkward for a few weeks but eventually you become a part of the team and begin actually understanding your job and what skills you need

I'm an aspie too so the social bit was hard to develop but I'm doing OK

>>55496599
No, but since I can't even seem to understand why this is happening I doubt I'd be able to make a test that can capture the bug.
It's a huge program with tons of functions and to do my work I need to call a ton of them, but I don't know how they're coded and something seems to be interacting wrong between my code and it.

I talked about it and no one understands why either.

>>55496677
then they bug might not even exist in code you've written, so you may need to test the functions you're using as well

i don't work btw

I have the function to turn:

Nichijou 01 audio:"en, jp, ru" width:1920 height:1080

into

'Nichijou 01', {'audio': '"en, jp, ru"', 'width': 1920, 'height': 1080}

now. Used Regex like someone in the previous thread suggested.
Right now I'm writing the SQL queries myself, which is sort of a pain but at least I'm learning something. I might end up swapping to SQLAlchemy in the future.

I think it would also be cool to have the "recently indexed" update without refreshing, but I do sort of want to avoid javascript.

thats a fair opinion. Plus its not like you need to keep the namespace clean if the only thing you're doing is looping once.

why are programmers always so retarded?

take an example: dropbox.

for the longest time double click on try icon would open the folder. now they removed it to "streamline" with gentoo or some shit. why would you remove a good feature instead of adding it to everyone or make it optional. now to open the folder you need to click -> move your mouse -> click again. fucking imbeciles. seriously.

>>55497803
Whoa! I too just wrote an object pascal fizzbuzz!

Any opengl programmers here? I stumbled upon a "hack" in someone elses code example where instead of using two separate buffers for vertices and UVs, they use a single buffer like this:

//verts is a vector of vec5s, first 3 elements are vertices, last two are UVs
glBindBuffer(GL_ARRAY_BUFFER, vbo);
glBufferData(GL_ARRAY_BUFFER, sizeof(verts), &verts, GL_STATIC_DRAW);
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 5*sizeof(GLfloat), (GLvoid*)0);
glEnableVertexAttribArray(1);
glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5*sizeof(GLfloat), (GLvoid*)(3 * sizeof(GLfloat)));

This seems pretty fucking great. Does this method have a name? Any juicy performance boosts?

>>55498141
that just looks like they've interleaved it

>>55498174
Yeah, now that I think about it the concept is pretty simple, but I never knew you can actually do that. Could probably pack normals in there as well with that method.

>interleaved
Yes! Thank you, this is the word for it. Gonna do some benchmarks with this interleaving method, pretty exciting.

>>55497913
It's shitty UX people who read "Principle 5: Consistency" and think that it means their application needs to be consistent across platforms. It doesn't, it means that it needs to be consistent with the other applications on that platform in order to conform to user expectations and make the application easier to use.

Spotify does the same thing and it's infuriating, even to someone that uses multiple operating systems. When I'm on my desktop my brain goes into Windows mode and I expect applications to behave like Windows applications, when I use my laptop I expect applications to behave like OS X applications.

    package I is new Ada.Text_IO.Integer_IO(MyRange);
begin
    for X in MyRange loop
        if X mod 3 = 0 and X mod 5 = 0 then
            T.Put("FizzBuzz");
        elsif X mod 3 = 0 then
            T.Put("Fizz");
        elsif X mod 5 = 0 then
            T.Put("Buzz");
        else
            I.Put(X, Width => 1); 
        end if;

            T.Put(" ");
        end if;
    end loop;

    T.New_Line;
end FizzBuzz;

>>55498141
Who uses separate buffers for vertices and UVs? Interleaving is just the standard method. It is not a hack.
You usually have one vertex buffer, and one index buffer.
The vertex buffer contains some number of floats per vertex which the shader reads.
It's very common to just do something like this:

struct vertex {
float pos[3];
float normal[3];
float uv1[2];
}

and then place an array of such structs in a VBO.

See https://www.opengl.org/wiki/Vertex_Specification_Best_Practices

>>55496284
In some cases you can pre-declare the class in a .h file as an extern, without having to specify its contents immediately.

Another good link, since I just realized that the other page I linked you doesn't definitively say that interleaving is preferable: https://www.opengl.org/wiki/Vertex_Specification#Interleaved_attributes
Of particular note is this quote:
>As a general rule, you should use interleaved attributes wherever possible. Obviously if you need to change certain attributes and not others, then interleaving the ones that change with those that don't is not a good idea. But you should interleave the constant attributes with each other, and the changing attributes with those that change at the same time.

>>55498503
source code pro

>>55499019
I think a good way is to work on a fairly simple problem without using a bunch of libraries and APIs (other than basic stuff like file IO and console IO,) and try to figure everything out yourself from scratch, rather than reading tutorials. Even if your solution is sub-optimal, it will be a good learning experience.


I'd recommend a fairly low level language if you want to really understand programming, something like C or C++.

So you might decide to write a simple text parser. Learn how to manipulate raw char arrays, and write and test some string handling functions. Reimplement strstr, strcmp, stricmp, etc.
Look up the spec for some file format and write a simple console-based utility to load the file and extract interesting information from the header, etc.
Forcing yourself to figure out how to do it on your own is really useful.

>>55499106
MPE's VFX

>>55496284

class Foo;

struct Bar {
    Foo* foo;
};

You don't need a class definition to make a pointer to an object of a particular class. Don't use void* unless you need a completely generic pointer.

>>55499192
Well I'm using C#, which I don't think is fairly low level.

I'm not sure if that will really help me, as my problem is more around the level of "I don't know how to utilize this APIs/libraries" (I'm messing around with monogame). The docs for monogame/xna don't really tell me a lot about what each library function does, at least in a way I can understand.

I will look at doing what you said though. No harm in more practice, especially if people say it will help you understand better.

Oh, well working with huge libraries that are poorly documented is always a nightmare, and I think it's actually bad for your problem solving skills - it encourages you to look up StackOverflow solutions rather than creating your own solutions based on a good understanding of the resources available to you.
If you have to use bloated APIs, then you'll have to learn a ton about them and essentially become an expert if you want to solve original problems well with them.

In C++, I'm trying to make an arithmetic progression of steps of 5 from 1 to 100, and trying to print a specific index that are label only by the elements in the arithmetic progression.
So far my code looks like
intVector1D nprint = {};
for(int k = 0;k<=100;k++)
{
if(5|k)
{
nprint.push_back(k);
}
return nprint;
}
if(nprint.count(n) = 1)
{
std::cout << "n = " << n << "\n";
}
Errors show up when I try to compile it, including how "count" isn't a vector operation.

Well, I'm not sure if it's just poorly doc'd, or if it's my inexperience. XNA is a microsoft framework, and monogame is basically a port after they ditched it.

While making games, I'm not sure if I'm better off honestly trying to write the huge amount of libraries that something like monogame provides, but at the same time, I see how it cripples my problem solving skills.

Quite a bind.

I took a year of programming in uni, so I can do basic, basic stuff like that. But I don't extend much beyond that. I know:

primitives
what an array is (not really how to use them well, though)
loops
if/else
methods

>>55499329
Yeah, I'm afraid there's probably no single correct answer.
Personally, I hate working with huge, hard-to-debug, opaque libraries. But I might have over-corrected a bit too far in the other direction, because I've built several game engines from scratch in various languages/graphics APIs, but never completed a game.
It's a lot of fun, a great learning experience, and it allows you to do real programming and problem solving, but it does mean a lot of time that you're not actually working on a game.
Arguably, if you don't care about working on engine development or cutting-edge graphics tech, your best bet might be to put your time and effort into learning a good API.

>>55499383
Fuck right sorry.

intVector1D nprint = {};
for(int k = 0;k<=100;k++)
{
if(5|k)
{
nprint.push_back(k);
}
return nprint;
}
if(nprint.count(n) = 1)
{
std::cout << "n = " << n << "\n";
}

>>55499391
muh sides

>>55499304
How are we supposed to know how intVector1D is defined?
Include more of your code, and put it in a code tag.
Also, your loop will always return on the very first iteration. I don't know what you were thinking.

>>55499391

god fuck

>trying to print a specific index that are label only by the elements in the arithmetic progression.

im assuming you mean you want to only print at certain intervals, which seems to be only when you have one item the collection

starting off, where are you getting the class/type definition for what a "intVector1D" is and/or are you correctly adding the header for it

i havent used c++ for awhile but i dont know how conventional it is that you can initialize an object with "{}", that's a javascript/python style thing

| is a bitwise operator and you probably meant something else, but even 5 || k wouldn't really make sense, look for the modulus operator

in your for loop you're returning out of the function (which since you didn't give the outer scope of this im assuming is main) which means it's just going to stop right there, just remove that return

going by what you said earlier and how i interpretted it, you should actually remove the brace after your wrong return statement because you want this conditional to be inside the loop

on nprint, if there was a size method it probably wouldn't take any arguments but you'd have to look at the api to know what it's called, it'd probably be either nprint.Count or nprint.size or nprint.Length

immediately after that you're using the assignment operator instead of equality check, = vs ==, and i'm not really sure why you only want to print if there's only going to be one item in the collection so you should probably rework that

you didn't fuck up the print statement atleast, but instead of using "\n" use std::endl

just redo it

>>55499452
No. Though I suppose I should? The class I took was pretty shit, and that book wasn't mentioned. I'll go check it out.

>>55497629

void FizzBuzz(size_t Num) 
{
    char* messages[4] = { "%i\n", "Fizz\n", "Buzz\n", "FizzBuzz\n" };
    for (size_t i = 1; i <= Num; ++i) {
        printf(messages[(!(i % 3)) + 2 * (!(i % 5))], i);
    }
}

>>55499501
also there's not even an n in scope, so either declare an n somewhere and use it or rework your logic to not include it since it actually isnt needed here, which should be easy enough

>>55499501
Yeah the return line is a mistake. Also the '|' was meant to be "divides". You''re right that it shoud probably be a mod.
n is defined elsewhere to run from 1 to 100. The nprint if loop is supposed to check if n is in the sequence.

Just started my first software job and I'm feeling very overwhelmed. I've got all the core programming concepts down, I've just never worked on a big piece of software like this before and I'm having trouble tracing everything and figuring out which parts do what.

Once I've learned a language, what do I search and what do I look for exactly to figure out which methods should be used and what the best way to do things are? It seems like theres always a one off blog post about doing something a particular way but no easy way to find these things out.

>>55499579
That's a bad idea. It's bad for readability, and should only really be done in a part of the code that you've profiled and determined needs to be sped up.
Worrying about that kind of thing for non-performance-critical sections of the code is a waste of time (and actually makes the code worse.)

Now I understand why some keygens, even from the scene are classified as Trojan.
That's because they use self-modifying code to protect their "secrets".
Self-modifying code is dangerous, that's not a normal behaviour of a program.

I really like a lot that they've done with it, but I think the goals are a bit too broad for now for a team of effectively two programmers who are busy parading around the language for a new academic paper every few months (which inevitability means adding another large feature that won't continue to be updated). If people stepped in to help out, it might succeed but the only way to do that is to get people to start using it, which isn't going to happen with the breaking changes on every release.

Why does DPT have such a massive hard-on for lambda calculus?

Because PLEASE DEACTIVATE YOUR TRIP CODE TO SEE THIS RESPONSE

Force of will.

>>55505152
Because lambda terms are the fundamental unit of computation

>>55505243

But nobody fucking uses them.

Neither, go for "C Programming: A Modern Approach" instead.

Sorry. Accidentally sent C++ Primer instead of C Primer.

Get C Primer, as I can't seem to find a pdf of it

Why would you link a C++ book?

pdfs

but m-muh deadtrees...But no seriously, I much prefer having something I can actually hold, flip through, highlight in, etc.

K&R is a classic, and an excellent book.
It's not a "learn programming" book though: it's a "learn C" book. It doesn't teach programming fundamentals and expects you to have basic programming knowledge going in.
If you're an absolute beginner, I don't recommend it.

I've heard good things about C Primer Plus, but I've never read it myself.

Does anyone know how to seek in stdout in Haskell?

>>55507535
hseek stdout

>>55507585

>handle is not seekable.

>>55507626
then you can't

>>55507638

There's gotta be some workaround,

>>55508066
make something that reads everything from stdout but saves it and you can get a handle to it
